Abstract
Process for obtaining reactive magnesium carbonate, characterized in that a levigation, especially aqueous, of magnesium oxide or hydroxide, or of substances containing these compounds, such as calcined dolomite or magnesite, is reacted with carbon dioxide or gases that contain it, maintaining a ph value of around 7.3 to 9.3 and because the hydrated magnesium carbonate or the reaction product that contains it, are separated and, if necessary, dried at temperatures below 200º c.
